Australian Prime Minister Malcolm Turnbull mocked US President Donald Trump in an off-the-record speech, imitating his speech style and rhetoric.

You know what they say: In the age of smartphones, there's no such thing as off the record. It's a lesson Australia's prime minister Malcolm Turnbull has learned the hard way.

On Thursday, Turnbull delivered a jovial speech at Parliament House's annual press ball, the equivalent of the White House Correspondent's Dinner.

In it, he made fun of the Australian government's dismal poll rankings. And he did so using a verbal tick made popular by a certain world leader.

"We get along great," Donald Trump has said of his relationship with Malcolm Turnbull. Time will tell what the notoriously thin-skinned President makes of Turnbull's speech.

In the speech, revealed by Australia's Channel Nine, Turnbull was heard making fun of his meeting with Trump in New York last month. "It was beautiful. It was the most beautiful putting-me-at-ease ever," he joked.

"Donald and I, we are winning and winning in the polls," Turnbull said. "We are winning so much. We are winning like we have never won before." To raucous laughter, he continued: "We are winning in the polls. We are, we are - not the fake polls, not the fake polls - they're the ones we're not winning in. We're winning in the real polls, you know, the online polls. They are so easy to win."

Australian Prime Minister Malcolm Turnbull could be heard poking fun at US President Donald Trump in the leaked audio.

Though the speech was off the record, it was recorded on a phone and broadcast by the Nine Network.

Turnbull also referenced Trump's Russia troubles. Referencing his supposed glowing polls, Turnbull asked: "Did you know that? I know that, did you know that? I kind of know that. I know that. They are so easy to win. I have this Russian guy."
